The REST Rhizome import request now requires the 'id' and 'version'
query parameters to either both be supplied or neither, and fails if
they do not match the manifest that is supplied in the request body.
Added a test case for this.
Added a test case to ensure that if the 'id' and 'version' query
parameters cause a hit (already in store) then the response is sent
immediately without reading the request body.
Improve the documentation for the REST Rhizome import request.
Users and contributors have had difficulty working out how to use the
more complex requests in the REST interface, particularly POST
/restful/rhizome/insert.
Improve the Markdown documentation to provide concrete examples of POST
requests and provide much more extensive description of how to use the
"multipart/form-data" Content-Type.
Adds a CLI and RESTful API operation for "keyring remove", with simple
test cases. Added the corresponding Java API operation. Updated the
API documentation.
API change: for consistency with RESTful API design, the GET
/restful/keyring/add operation now returns "201 Created" not "200 OK" if
successful.
